Tiny microheaters that can prompt chemical changes in surrounding material may provide the means to more easily grow replacement tissue for injured patients and form the basis for medical sensors that could quickly detect pathogens, according to researchers at the University of Washington who are the first to demonstrate the process.
The key to the technique, according to Associate Professor Karl Böhringer in the UWs Department of Electrical Engineering, lies in temperature-driven changes in the material with which the less-than-one-millimeter-wide electric heaters are coated. Proteins stick to the material as its temperature rises, and release when it goes back down. That, according to Böhringer, opens the door to a wide array of possibilities.
"The proteins stick locally to the areas we heat, and we can stick cells to the proteins," he said. "This provides a relatively simple, low cost way of creating cell chips to run experiments and to create other useful devices."

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
